Eddy Covariance (H2O/CO2)
Eddy Covariance (H2O/CO2), surrounding area
The continuous observation of the energy balance components is essential for understanding the exchange processes between tundra soils and the atmosphere. Toward this goal, we set up an open path eddy covariance system in the vicinity of the existing metrological station on Samoylov Island at the end of April 2007. The system is capable of measuring fluxes of sensible heat, water vapour and thus latent heat, as well as CO2. It consists of a CSAT3 sonic anemometer and a CS7500 open path CO2 and H2O gas analyser.
Eddy Covariance (H2O/CO2), set-up
The period of eddy covariance measurements on Samoylov Island is still limited. The gas analyser unit is only operational during the summer season due to the harsh weather conditions and risk of damage during the winter period. The period of observation is also restricted by the data storage capacity of the system.
The power supply of the eddy covariance system, as well as the other meteorological instrumentation, rely on solar power and wind generators which allows operation during the polar night.
Other meteorological parameters are measured at the long term climate and soil stations near the Eddy Covariance System (see Samoylov soil and climate station).
